Head Matkivskyi Ostap M., Registration Date 11-02-2021 Organization Vasyl Stefanyk Precarpathian National University, State Higher Educational Institution popup.description1 The project involves the research and manufacture of multilayer solar modules of the second generation based on semiconductors ZnO / CdS / CdTe / CuO and optimization of the efficiency of the obtained modules. Theoretical calculations indicate the prospect of using these materials in thin-film solar energy industry. The obtained thin films of zinc oxide as the upper resistive layer are characterized by a homogeneous structure with a columnar growth mechanism, which leads to better light absorption. Photovoltaic modules based on them have high efficiency values and reach the level of 22.5%. Thin-film modules, in which CdTe is used as an active material, are considered the most promising due to the cheap and reproducible technology of vapor deposition. The authors of the project have developed a reproducible technology for obtaining thin-film heterostructures with a given surface morphology during vacuum deposition, which contributes to their low cost. The critical dimensions (thickness) of individual layers of the heterostructure are substantiated, modeling is carried out and a wide range of optical properties is investigated. It is shown that an efficiency of 15.8% can be obtained for the deposition of CdS / CdTe heterostructure on a glass substrate. According to the current data analysis, the efficiency can be improved by applying a layer of ZnO and a CuO backing layer to the films. popup.nrat_date 2024-12-09 Close
